Hi all,

Yes, I do apologize for the extremely short notice on this one (especially after pulling similarly short notice last time as well)...I've been busy as ever but nonetheless really should have gotten this out much earlier. :-| Hopefully people will still see this in enough time to catch the start of the rally, or at least not miss too much at the beginning...

We will be having another week-long rally on our port 2000 PRPnet port from Wednesday, April 18 at 7:00 PM GMT to Wednesday, April 25 at 7:00 PM GMT. (That is, 3 PM EDT and 2 PM CDT in the United States.) As last time, we'll be focusing on the 14th Drive, which covers the range of k=600-1001, n=1M-2M, and are presently in the vicinity of n=1.12M. Primes found at this level are nice, big juicy ones--they come in at about 1000th-1500th place on the Prime Pages' top-5000 list. :-)

My past announcements here have grown increasingly verbose with each passing rally, so I'll cut out a lot of the largely unnecessary dross this time and cut to the chase. :-) If you are interested in more general information/historical background about the project, you can check out this thread over at the NPLB forum and get a much more concise intro. So without further ado:

-The server for this rally is running PRPnet, on noprimeleftbehind.net port 2000. The line to put in prpclient.ini is:

server=NPLB_2000:100:1:noprimeleftbehind.net:2000

(A cache size of 1-3 pairs is recommended. The tests will be in the vicinty of n=1M-1.1M during the rally. They've been taking about 7-8 minutes apiece on my Core i7-2620M computer with llrAVX; reasonably modern computers without AVX will probably take about 12-18 minutes per test.)

-Any primes you find should be reported as "[your name], NPLB, srsieve, psieve, LLR" at the Prime Pages website.

-Stats for the rally will be posted at http://www.noprimeleftbehind.net and updated hourly. Once the rally is complete, the stats will be archived here.

-If you have any questions about NPLB or the rally, please feel free to post either here or in our main rally thread at the NPLB forum--both places will be monitored by the NPLB admin squad. You can also email me at max@noprimeleftbehind.net.

Hope to see you there!

Max :-)
